At first place, it's a greatt acheivement that IR has been able to complete the Doubling of 602/620 kms on Kerala Trunk route...
The remaining 18 kms stretch will also be completed in future...
I still remember my frequent visits to Calicut/Kozhikode during 2006-2008, when doubling had just started there & locals were telling that it might never be completed thanks to the apathy from state govt & land acquisition issues in Kerala..
